IMPROVEMENT IN CEMENTS FOR'COAT'ING AND SEALING COFFINS, 8w.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Beit known that I, ISAAC CHARLES, of the cityand county of Allegheny and State of Pennsylvania, have invented'acertain new and useful Oement for Hermetically Sealing Bulial Gasketsand Ooffins ;and I do hereby declare that the following is a full,clear, and exact description thereof.

The nature of my invention consists in mixing beeswax and asphaltumtogether so as to form a hard, flexible, and adhesive cement for closingthe joints, coating the interior and exterior surfaces of, andhermetically sealing burial caskets and coffins.

' To enable others skilled in the art to make and use my invention, Iwill proceed to describe more fully the process of making and using thesame.

I take a good article of beeswax, about one (1) part, and a good articleof asphaltum, about fifteen (15) parts. I melt, in a suitable vessel,the asphaltum, and as soon as it is completely liquid add the beeswax,so stirring and mixing the articles together as to form onethoroughly-mixed and homogeneous mass. The stirring of the meltedingredientsshould be continued after the vessel has been removed fromover the fire, and until the mass has become sufficiently congealed toprevent any separation of the two ingredients.

In applying the cement to the joints of cofl'ins, or coating theirsurfaces, and for sealing on the lids,-I melt the cement,and, with asuitable vessel, pour it, while hot, in, on, along, and over the jointsof the coffin until every joint and crevice in it is covered andperfectly closed and cemented.

The surfaces ofthe casket or coi'fin are coated with the cement bypouring the meltedand hot cement on the surface to be coated and thenrubbing and smoothing it down with a hot metal roller or other suitabletool or device.

The lid of the casket or cofiin is sealed on its body by pouringthecement while hot along and around on the top edges of the sides and endsof the body of the casket or coffin, and then securing the lid to itsplace by means of screws or nails.

It would be of advantage to have a groove made in the top edges of thesidesand ends'of the casket or coffin for the purpose of receiving andholding the cement;

but the lid may be securely sealed on the body withu out such groove.

The hereinbefore-described cement being hard, flexh ible, and veryadhesive, and also impervious to air and water, burial-caskets andcoflins constructed of forth.
